This page provides an overview of the available methods on the Chainstack Optimism nodes. Go ahead and try the interactive examples as well. Chainstack Optimism Global Nodes and Trader Nodes both run op-reth, so method availability is the same across tiers. Debug and trace methods require debug and trace APIs to be enabled on the node.
The list may not be comprehensive but serves as guidance. In general, if a method is available in op-reth and it’s an eth_ method, then it’s available on your Chainstack node.If there’s a method missing, you are unsure, or just have any questions, talk to us. We love talking to developers .
op-reth also supports the trace_ namespace (for example, trace_block and trace_transaction); these require debug and trace APIs to be enabled. See the Base methods reference for the full op-reth method set, which is shared with Optimism.
